Basement finishing in Deerfield, IL
Basement finishing in Deerfield often transforms the lower levels of mid-century ranches, split-levels, and colonials, converting underutilized space into vibrant, functional areas. These homes typically feature basements that are either unfinished or have rudimentary, older finishes, ripe for a modern overhaul. Our projects frequently involve taking these raw concrete spaces or dated recreation rooms and reimagining them as contemporary living areas tailored to the family's needs. We address the unique structural and age-related considerations of Deerfield's housing stock, from foundation conditions to the integration of new electrical and plumbing systems into existing frameworks. The goal is always to create a seamless extension of the main living space, adding significant value and usability.
What Deerfield homeowners ask for
Deerfield homeowners frequently request dedicated home offices or study areas within their finished basements, given the prevalence of remote work. Family recreation rooms with built-in entertainment centers are also highly sought after, providing a distinct zone for leisure. Many projects include the addition of a full or half bathroom to enhance convenience and functionality, especially when creating guest suites.
About Deerfield
Deerfield's housing stock tells the story of the postwar boom, with ranches, split-levels, and colonials filling former farmland. Remodeling that stock is what we do, opening up mid-century floor plans for how families live now.
The village grew from about 3,300 residents in 1950 to nearly 12,000 by 1960, filling former farmland with the ranches, split-levels, and colonials that still line its streets, with later construction as the population grew toward today's roughly 19,000. Families here anchor around District 109 schools, Deerfield High School, downtown's Deerfield Square, and two Metra MD-N stations at Deerfield and Lake Cook Road.
The rapid growth from 1950 to 1960 means many basements in Deerfield's ranches, split-levels, and colonials may have lower ceiling heights and lack modern drain tile systems, necessitating careful planning for headroom and moisture control. The prevalence of homes built before 1960 indicates potential for lead water service lines, which, while not directly impacting basement finishing, suggests the original plumbing may be due for updates during any basement bathroom additions. The former farmland setting can contribute to moisture challenges, making effective waterproofing and sump pump solutions essential for creating dry, habitable lower levels. Mechanicals in these mid-century homes are often centrally located, requiring strategic design to integrate around existing furnaces and water heaters without compromising usable space. Egress window installation is a common requirement to meet current safety codes, especially when transforming these basements into bedrooms or extended living areas, ensuring safe exit routes.
For basement finishing in Deerfield, inspections are critical at various stages, including framing, electrical, plumbing rough-ins, and insulation, before drywall is installed. GS Construction & Remodeling manages all permit applications, ensuring all necessary documentation is submitted and coordinating the Village of Deerfield's inspection schedule for each phase of the project.

I don't even know where to begin, Patryk & Greg are just amazing! We hired them to remodel approximately 4000 sqft of a 1985 house which included an unfinished basement. The whole experience could not have been better. It took about 7 months and for most of it, we lived in the house with two children. They are incredibly professional, can troubleshoot any issue and are 100% dependable. Patryk led the project and he was very detail-oriented. Everything had a purpose and was finished with beautiful extra touches. I changed my mind frequently and they didn't miss a beat. They worked around the changes and kept moving. The materials they used and the teams they brought in were all top notch. They didn't spend money where it wasn't necessary and in fact, they were always trying to find ways to save money. Finally, they are really nice guys. Polite, respectful and very accomodating. After spending so long in my house, we (almost) miss having the around. As I mentioned, we had the whole house remodeled and its impossible to post every picture so I will showcase just a few highlights. The whole house is beautiful! Scott & I THANK YOU!!!
